Hi,
After spending months banging my head over Earley Parsing, I have
decided to write a tutorial. Ian once said Earley parsing is simple
and easy to implement. I agree with simple, but not with easy.
The required background knowledge is not trivial.
This tutorial is an attempt to gather this
Hello,
I am currently trying to implement Earley Parsing. My ultimate goal
is to combine all the advantages of OMeta and Earley parsing:
- OMeta can handle some context-sensitive grammars.
- OMeta's prioritised choice have obvious semantics.
- Earley work on left-recursive grammars out of the

Terrific work! I have just cloned your git repository, I will check
it out.
But first, I need to crack generalised Earley Parsing. I love OMeta,

is ugly (meaning, not fully general).

Originally, the VPRI claims to be able to do a system that's 10,000
smaller than our current bloatware. That's going from roughly 200
million lines to 20,000. (Or, as Alan Kay puts it, from a whole library
